Fig. V is a detail sectional view on line 5-5 of Fig. III, showingthe contour of the main cutter and its manner of support.

F ig. VI'is a detail sectional View on line 6-6 of Fig. IV, showing the arrangement and supporot of the dado saw tooth cutter for cutting the tenon' groove around the spoke.

In the drawing similar numerals of ref-.

erence, refer to similar parts throughout the several views and the sectional'views are taken looking inthe direction of the little arrows at the ends of the section lines.

Considering the numbered parts'of the drawing by their numbers, 1 is the shaft.

2 is the hub. 3, 3 the supporting plates 5 is a and a the cross bars of the head. cutter blade with the curved end part 6 corresponding tothe contour of a spoke or part to be turned held in place by screws dado saws 10 and supported between the straight projecting ends of the main cutter blade, so that the cutter head will not only turn the body of a spoke but will also cut an annular rim around the same to form the tenon. It is clear that the details of this structure can be greatly modified without departing from the invention;

Having thus described the invention, what desired to secure by is claimed as new and Letters Patent, is:

The combination of a cutter head with main blades curve-d at one end and. straight at the other, and a spider with obliquely disposed saws at the outer ends of its arms disposed between the straight ends of the said blades whereby a groove is cut at the same time the specified.
